The NFL is reviewing Detroit Lions defensive tackle Ndamukong Suh's low block on Minnesota Vikings center John Sullivan in Sunday's season opener, and Ray Anderson, the league's executive vice president of football operations, said a suspension has not been ruled out as possible punishment.

"All options are on the table with a repeat offender," Anderson said by phone this morning. "You can honestly say it's being reviewed for either a fine and/or a suspension, given his repeat-offender status."

Suh was fined five times in his first three NFL seasons and suspended for stomping on the arm of Green Bay Packers offensive lineman Evan Dietrich-Smith in a Thanksgiving incident in 2011.

Last year, he was fined $30,000 for kicking Houston Texans quarterback Matt Schaub in the groin on Thanksgiving. As a rookie, he was fined three times, twice for hits on quarterbacks Jake Delhomme ($7,500) and Jay Cutler ($15,000) and once for using an opponent for leverage on a field goal ($5,000). And in 2011, he was fined for a preseason hit on Andy Dalton ($20,000).

On Sunday, Suh was called for a personal foul when he dived at Sullivan's knees as the Lions' DeAndre Levy returned an interception on Minnesota's opening drive of the second quarter.

Suh said he didn't intend to hit Sullivan low and that the two talked about the play at halftime.

"By any means, I'm not going for his knees," Suh said after the game. "He knows that. We had a great conversation running out at halftime. And he understood. My aim was his waist, to cut him off."

Sullivan had his knee checked but did not miss a series.

Sullivan told the St. Paul (Minn.) Pioneer Press he could have suffered a serious injury. "I don't know how it wasn't," he said. "I just watched it (on film). That was bad."

Said Vikings coach Leslie Frazier: "The fact that they got a penalty called, that tells you it wasn't a good play. You hate to see guys go low on players. We've seen the results of it. So it's not a good thing to happen."

Vikings defensive end Jared Allen also said Suh's hit crossed the line.

"I got to know Suh at the Pro Bowl last year, and he's a good dude," Allen said. "But that's uncalled for. It really is. This is a fraternity. In the NFL, you try and take care of guys.

"Granted, things happen and guys are going to make hits and some things are going to be borderline. But you can't take a dude's legs out from behind on an interception when he's running down the field. To me, there's just no room for that."

Anderson said the league will make a decision on punishment for Suh by midweek.

"It's under review through our normal process and until that's complete, I can't give you any information," he said. "But it's being reviewed."
